Engineered Stainless Steel for Demanding Applications

At Spokane Stainless Technologies, we design and build stainless steel vessels, tanks, and skids for pharmaceutical, ASME, and corrosion-resistant applications, ensuring compliance, durability, and seamless integration.

Why Certification Matters

Engineering, fabrication, and installation must meet strict industry regulations to ensure product safety, process efficiency, and environmental responsibility. Certification ensures:

  • Compliance with federal, state, and industry-specific regulations
  • Safer equipment operation and extended service life
  • Third-party verification of material quality and construction integrity
  • Reduced risk of operational failures, contamination, or regulatory fines

  • Regular audits and compliance inspections verify ongoing certification status

Frequently Asked Questions

ASME certification ensures that high-pressure tanks meet engineering, material, and safety requirements set by federal and industry regulators. It is required for many aerospace, chemical, and fuel storage applications

ASME U applies to full-size pressure vessels, requiring third-party inspections. ASME UM is for miniature vessels with reduced inspection requirements.

UL 142 is required for aboveground storage of flammable and combustible liquids in fuel, distilling, and chemical industries.

Yes, if transporting hazardous materials over public roadways, DOT 406, 407, or 412 certification is required based on the material classification.

Yes, we hold the ASME R Stamp, which authorizes us to modify and repair ASME-certified pressure vessels while maintaining compliance.
